Covid-19 can 'age' the brain in up to 10 years

A major study led by Imperial College London, involving 365,000 participants in England and conducted between 20 June and 28 September, showed the number of people testing positive for antibodies fell by over 25 percent across the study period - from nearly roughly six percent to 4.4 percent.

In their findings, the researchers' analysis of the home finger-prick tests found that the number of people testing positive for antibodies dropped by 26.5% during the study period, from nearly 6% to 4.4%. One study finds patients lacking vitamin D are twice as likely to develop a severe coronavirus infection.

The evidence follows several studies published earlier this year from China, the United Kingdom and the U.S., which found that people's antibody levels declined sometimes as early as two months after infection.

The downward trend was observed in all areas and across all age demographics, except for healthcare workers, which probably indicates higher initial exposure to the virus, or repeated exposure, among this group.

A team from the University of Cantabria and Hospital Universitario Marqués de Valdecilla reveal 80 percent of 216 patients testing positive for COVID-19 had vitamin D deficiencies when they entered the hospital.

The FDA-authorized rapid antibody tests will use a finger-prick blood sample and will be available at all Kroger pharmacies and clinics by the end of November.

World Health Organization spokesman Tarik Jasarevic said that uncertainty over how long immunity would last and the fact most people had never had antibodies against the coronavirus in the first place showed the need to break transmission chains.

"Our study shows that over time there is a reduction in the proportion of people testing positive for antibodies", said professor Paul Elliott, director of the programme at Imperial College London. The decline in antibodies - blood proteins produced by the body in response to an attacking antigen - was seen across all age groups, but the largest drop was seen in the 75+ age group (a decline of 39 percent) and the smallest in the 18-24 age group (14.9 percent). "We don't yet know whether this will leave these people at risk of reinfection with the virus that causes COVID-19, but it is essential that everyone continues to follow guidance to reduce the risk to themselves and others", said professor Helen Ward, one of the lead authors.

But scientists involved cautioned that a great deal remains unknown about people's long-term antibody response to the virus.

Most importantly right now however, previous studies have continued to link vitamin D deficiency to worse COVID symptoms.

"These findings suggest that there may be a decline in the level of immunity in the population in the months following the first wave of the epidemic", per the university release.

Research is still underway to determine how long antibodies are present after infection and if that presence provides immunity.
